Application med April a, 1909. serial No. 487,579.

`To all whom; it may concern:

Be it known that I, OSCAR L. NEISLER, of Indianapolis, county of Marion,and State of Indiana, have invented a certain new and usefulStreet-Sweeper; and I'do hereby de- Clare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, in which like letters refer to like parts.

The object of this invention is to provide a satisfactory brush streetclean-ing machine, one that is particularly suitable for being pushed byhand.

One feature of the invention consists in combining with a machine aremovable dirtreceiving box, a brush in advance thereof adapted toengage the surface of the street, and a conveyer for conveying the dirtfrom the brush and discharging it into the box. When the box becomesfilled it is removed and another one put in place, and the filled boxesare taken u and carried away by a wagon. Along with the foregoing listhe idea of au adjustable inclined upper front wall for the dirt box, soas to adjustit to the discharge end of the conveyer.

Another feature consists in hinging doors over the conveyer,vone aboveand 011e below so as to render the entire conveyer accessible ifnecessary.

Still another feature yconsists in the combination of a peculiar clutchmechanism on each side, one for throwing the conveyer and the other thebrush into and out of operation, and a connection between said clutchmeans and the handles, whereby the pushing of the handles will tend tohold the clutches in engagement, while when the clutches are out ofengagement the handles are turned rearwardly for use while merely`transporting the machine.

The nature of the invention will be understood from the accompanyingdrawings and the following description and claims.

In the drawings Figure 1 is an elevation of the left-hand side of themachine. Fig. 2 is a perspective View of the dirt box. F ig.' 3 is acentral vertical section through the machine, the obscured parts beingshown by dotted lines. Fig. 4 is a vertical section on the line 4 4 ofFig. 3 through a portion of the machine. Fig. 5 is a diagonal crosssection through the right-hand side of the driving mechanism and frameto illustrate the clutch mechanism, the released position being shown byfull lines, and the engaging position of the clutch being indicated bydotted lines. Fig. 6 is a plan view of a ortion of the side of thedevice shown in ig. 1. Fig. 7 is a detail of one of the handles.

A pair of suitable track wheels 10 are mounted on solid spindles 11extending laterally from side frame bars l2, that are inclineddownwardly from the rear to the front of the machine. A' U-shaped bar 13connects said side frame bars 12 to the rear of the spindles 11, so thatsaid U-shaped bar 13 forms part of the frame of the mawheel, there is areinforcing segmental plate` 2() secured, and beside and outside it anarm 21 projects upwardly radially of the wheel and beyond the peripheryof the wheel, and carries the rod .22 that extends across the machineabove the conveyer 23. This conveyer is mounted on an actuating roll 24at the upper end and an idle roll 124 at the lower end. The actuatingroll is mounted on a shaft 25 that extends transversely of the machineand is mounted in the two side plates 26. These side plates are rigid,one on each side of the conveyer and furnish the side walls fortheconveyer casing. They are bolted securely to the arms 21 by bolts 27passing through spacers 28. The lower ends of said side bars are mountedon the lower conveyer roll 124 and are held in place by it as it extendsthrough said side i plates 26. Said lower conveyer roll 124 is reducedat its ends, see Fig. 1, and such reduced ends have bearings in thelower part of the posts 30, which are secured at their lower ends to thefront ends of the side frame bars 12, and are held in a verticalposition. Hence it is observed that the side plates 26 are stationaryand the conveyer moves between them. The under side of the conveyer isunprotected excepting as it rides over the inclined wall 32 of the dirtbox 16, as seen in Fig. 3. There is a cover over the conveyer, the uppercover plate 34,

which at its' lower end is hinged on the rod 22, and a lower cover plate35, which at its upper end is hinged on the same rod 22. The sides ofthese cover plates are turned downwardly at right angles to the bodyportion thereof so as to inclose the plates 26 at the sides of theconveyer. Hence access is readily made to the conveyer by opening eitherthe top plate 34 or the bottom plate 35. The brush 41 is a cylindricalone with its shaft 42 mounted in the brush supporting bars 43. It isextended on the right-hand side of the machine'and carries a sprocketwheel 44, which is driven by the sprocket chain 45 from the largesprocket wheel 46, mounted on the sleeve 47, that is longitudinallyslidable on the spindle 11, as shown in Fig. 5. The adjacent ends of thehubof the wheels 1() and 46 are toothed so as to engage and clutch eachother, when the wheel 46 is moved toward the wheel l0. This clutchmovement is caused by the long clutch bar 48 fulcrumed to the frame bar12 at 49 and run through the slotted outer end of the sleeve 47, and atits upper end pivoted at 50 to the handle 51, which also at its innerend is pivoted at 52 in a recess of the side frame bar 12. When thehandle 51 is in the dotted line position shown in Fig. 5, the clutchesof the wheels are in their interlocking position, and when in the fullline position the clutches are disengaged.

The brush supporting bars 48 have a plurality of holes 60 to receive theends of the brush shaft 42, so that said brush may be adjustablymounted. Said bars are pivoted at 61 to the side bars 12 of the frame,and therefore the brush can ride up or down according to the surface ofthe street. The bars 43 extend through vertical slots in the posts 30,which guide them in their vertical movements, and they are held down bya spiral spring 62 in said posts, the tension of which is adjusted bythe set screws 63. There is also a scraper 64 extending the full widthof the machine, in fact, beyond the ends of the brush, which scraperrides upon the surface of the street and at its inner end is pivoted tothe inner sides of the plates 26 beside the conveyer by means of pivots65. There is a gear wheel mounted on the sleeve 47 in the left-hand sideof the machine, which sleeve is mounted on the spindle 11. The adjacenthubs of the wheels 10 and 70 on the left-hand side of the machine aretoothed so as to clutch-in fact, the construction and mounting of thesewheels are the same at the left-hand side of the machine as at theright, which is shown in Fig. 5, and there is also on the left-hand sidethe same sort of clutch bar 48 arranged and operated in the same way asthat shown in Fig. 5, for throwing the wheel 70 into and out ofoperation. The wheel 70 meshes with the spur gear 72, which is securedon the sleeve 73 mounted oh the rod 22. Said sleeve also carries asprocket wheel 74 from which a sprocket chain 75 extends over thesprocket wheel 76 and drives the roll 24 of the conveyer and whereby theconveyer is operated. Thus it is seen that the brush actuating mechanismand the conveyer actuating mechanism are similarly thrown into and outof operation by handles 51 at the rear. The operation and construction4are not only similar, but the operation is simultaneous. When the twohandles 51 are in their inclined position, the machine is in operatingcondition, and when the machine is not in operating condition, thehandles 51 extend rearwardly and then can be used for propelling themachine.

As the machine is pushed forward in operation the brush sweeps the dirtup on the scraper 64 and throws it on the lower end of the conveyer,which moves it up and discharges it into the dirt box. This dirt box hasa sliding inclined top plate 80, see Fig. 2, the upperedge of which isadjustable with relation to the upper end of the conveyer so as to leavean opening of the right size for the discharge of dirt on the con`veyer. The plate 8O slides under the stationary top plate 32, therebeing space enough between said stationary -top plate and the sides ofthe box to permit said plate 80 to be slidable. There is a horizontaltop plate 81 in the nature of a lid that is hinged at 82 so it can beturned back for discharging the contents of the box. To assist 1nmanipulating the box it has a handle 83 on each side. v It can bereadily lifted olf the plate 15 and also readily inserted in place onsaid plate 15 and between the flanges 17 and 18, whereby it is held inposition.

What I claim as my invention and desire to secure by Letters Patent is:
